When machines fabricate plastic parts, the cutting tools work to create the desired shape in a piece of plastic. The machine will stretch the plastic past a point where it can return to its original shape. As the machine stretches the plastic beyond its original shape, it may crack or fracture the plastic. As a result, burrs form.
